Abstract: The invention relates to an injector-pump unit for diesel engines, in which an injection-pump element having a pump plunger (3) driven by a camshaft via a pressure piece (6) and having an element bushing (1) is combined with an injection nozzle to form a unit which is to be assigned to in each case one engine cylinder, the pump plunger (3) being surrounded by a control sleeve (17) mounted non-rotatably relative to the element bushing (1), and the pump plunger (3) being rotatable relative to the control sleeve (17) by a quantity-adjusting device (10, 37) to adjust the delivery quantity. The quantity- adjusting device (10, 37) is arranged at the level of the pressure piece (6). The control sleeve (17) is arranged entirely within the pump spring (4). The pump spring (4) partially surrounds the element bushing (1), which is of integral design with a blind hole (2) for accommodating the pump plunger (3). The pump spring (4) extends from the level of the quantity-adjusting device (10, 37) to the level of the working space (7) of the pump plunger (3). In this way, a nested arrangement of the individual parts of the injector-pump unit is obtained, the overall dimensions of the injector-pump unit thereby being kept small.

Abstract: Des outils de plissage servent à former simultanément et à aplatir dans une pièce de tissu un pli double (DF) et une pluralité de plis simples (SF) latéralement espacés de ce premier. Les outils de plissage sont soutenus sur trois paires de planchettes superposées (86/87; 88/89; 90/91), dont la première est formée par deux planchettes (86, 87) mutuellement reliées par une charnière et mobiles entre une position droite et une position pliée. Les planchettes (88/89; 90/91) des deuxième et troisième paires se déplacent toujours en sens inverse l'une de l'autre et des planchettes de l'autre paire. Ces planchettes (88/89; 90/91) de la deuxième et de la troisième paire de planchettes portent chacune au moins une lame de plissage (111 ou 110), alors que la première paire de planchettes porte les dispositifs de retenue correspondants (112). La position relative de la première paire de planchettes (86/87) par rapport aux deux autres paires de planchettes (88/89; 90/91) est modifiable. Le dispositif est utile pour fabriquer des articles caractérisés par une pluralité de plis de formes diverses, par exemple le dos de corsages et de chemisiers.

Abstract: A coffee-maker (1) with a brewing device (7) is described which has a brewing chamber (9) and a piston (37) which can move back and forth therein. One of the end sides of the brewing chamber (9) contains an opening (44) which is exposed by a closure member (8) in one of its positions (I) for metering in ground coffee and is closed in another position (II). A scraper (48) is provided for scraping and ejecting the coffee dregs. In order to simplify a coffee-maker of this type in terms of construction and to design it to be more reliable and robust in function, it is proposed to move the closure member (8) only in a plane running parallel to the opening (44) relative to the brewing chamber (9) and to link the scraper (48) to the closure member (8) in its movement.

Abstract: Work lamps such as those which are preferably employed in office system work places put high demands on a uniform illumination of the working surface without dazzling the user in the process. As shown in practice, the necessary screening of the fluorescent lamp arrangement leads to disturbing reflected images, particularly given a low lamp installation height. It is proposed to provide the fluorescent lamp arrangement (LL), which is located here at the rear side of the housing trough (G), with a flat main reflector (R1), which is inclined forwards and reaches as far as the front edge of the housing trough (G), and with an auxiliary reflector (R2) below and in front of the fluorescent lamp arrangement (LL), which makes it impossible to see into the fluorescent lamp arrangement (G). The light exit opening is covered in this arrangement by a diffusing panel which has a fine prismatic structure on the lamp side. <IMAGE>

Abstract: The integrated optical circuit has at least one semiconductor component (1) having an optical wave guide part (11, 31) for conducting a TE mode and TM mode. The semiconductor component (1) is an electro-optical heterostructure (2) having an electrode on the substrate underside and a further electrode (13) on the optical wave guide part (11), which is narrower than the optical wave guide width. Linear and quadratic electrooptical effects, as well as the free charge carrier density and the ''bulging'' electrical field, generated by applying a voltage, between electrodes, causes in the case of a specific voltage a phase shift of the TE and TM modes in the optical wave guide branch (31) of the semiconductor component (1) integrated in the Mach-Zehnder interferometer (33) by comparison with its second optical wave guide branch (30) without a semiconductor component (1) from an integral multiple of the half wave length. It is thus possible to use the Mach-Zehnder interferometer (33) as an intensity modulator, polarisation-independent switch, separating filter or polarity separator. <IMAGE>

The second loop extends outwardly, preferably radially, of said element and has a precise interior volume. Appropriate interior passageways are provided in the outer elements for directing a liquid sample in a continuous path through the valve assembly, the path including the one segmenting passageway and the first and the second external loops. Additional interior passageways also are provided for coupling the valve assembly to sources of diluent and to exterior destinations. The central element is rotated to isolate the contents of the segmenting passageway and of the first and the second external loops and diluent is fed thereto to drive the isolated contents to said destinations. Only a single loading step is required to obtain three precise volumes of liquid sample. The valve assembly can be rinsed and continuous internals channels are provided for preventing any liquid from reaching the circumferential surface of the valve assembly.
